` CONsTRUcTiOn'OEDRYINQMACHI Esiwrrn:nofranrimnrnsnnvlcnsl To all whom t may concern.'y f, y f f Be 1t known that we,'R1oHARD S 1MON, WILLIAM `GEORGE SIMON, and `FREDERICK RrOHARo S1MoN',`-subjects of the `King of f Great Britaimresiding at Basford,.l\l ottingham, England, have invented certain `new and useful Improvements in or RelatingtoV the Construction of Drying-Machineswith Rotary Heating Devices, of Qwhich thefol` lowing is a speciication.

.1 In, order to obtain a maximum heating directly fromV the feedingv chamber, or device. At the same time, means are also provided to diminish torsionalstrain and more particularly to obtain control ,overy the lenergyofthe drying process at its initial. and final stages at whichthe condition of the' material yis that is being dried.7 l The invention, specifically,1 consists of two bundles or nests of uncovered heatedtubes, placed longitudinally in the trough of the machine, and each nest driven separately at opposite ends by means of suitable gearing froman outer The trough in which the uncovered heatedtubes revolve may, vif desired be made with a chamber or chambers for heating the material to be dried'in addition to theheated tubes.

vIt is a further feature of the invention to provide rotatable supporting' disks adapted to support the nested tubes in position, and

form` therewith in the Aform ,of `a revolving drum, said disks being formed with achamj-f,V

ber communicating with the tubes, and suitably connected with a supply of a heating element. It is, also, a feature of the inven-- tion to provide each rotatable drum, formed by the tubes and disks, with a centrally eX- tending enlarged conduit or passage connecting with the chambers of said disks, which passage is so arranged with respect to the feed from the supply source as to permit a free circulation of the heating element of the material to be dried.

through said tubes;

The invention further consists in certain drawings. f

will `thusbe -fseen 'thatthe above construc.-

tion provides 4two independently rotatable drums formed of bundlesor nests 'of heated tubes longitudinally disposed in thev trough l. '-Each'drum G and'H has extending centrally therethrough the .conduit or passage 7 of acomparatively larger vdiameter than the diameter ofthe tubes. The conduit 7 communicates through the plates l with the chambers 5 ofthe disks of each drum which, according tothe presentconstruction shown and described, has'y an independentheat circulation so that different pressures or calories '0f heatmay be supplied to either of ther drums, according to the nature :or character The end orrouterfdisks of each drum` G and H carry rigid therewith the 1 sprocket Wheels C and D,lrespectively, disposed Withoutthe trough "1. A 'shaft "A' mounted upon the trough of the machine and parallel'therewith is .fdriven by..any..suitable means. and` has keyedv thereto the sprocket WheelsfB, over which a suitable ,sprocket chain,p.asses,
